“If GM had kept up with technology like the computer industry has, we would all be driving $25 cars that got 1000 MPG” (Bill Gates)
“I think there's a world market for about five computers” (Thomas Watson)
The Abacus
May have been invented in Babylonia in the fourth century B.C.
Helps the user remember the current state of the calculation

Jacquard Loom
Mechanical loom invented by Joseph Marie Jacquard in 1804
Controlled by punch cards that describe the design of the textile
Precursor to programming

Ada Lovelace
Augusta Ada Byron described on the Analytical Engine as weaving “algebraic patterns just as the Jacquard loom weaves flowers and leaves.”
Published an analysis of the Analytical Engine. In it she outlines the fundamentals of computer programming, including data analysis, looping and memory addressing.

Atanasoff-Berry Computer The Atanasoff–Berry
Computer (ABC) was the first fully electronic computing device. It was successfully tested in 1942.
The ABC used binary arithmetic, electronic switching, and stored programs.
The ABC had been examined by John Mauchly in June 1941

Colossus
Colossus, a British computer used for code-breaking, is operational by December of 1943
The Colossus machines were by British codebreakers to help read encrypted German messages during World War II.
An improved Colossus Mark 2 first worked on 1 June 1944, just in time for the Normandy Landings.

The Harvard Mark I
Designed in the 1930s by Howard Aiken. Built in collaboration with IBM
Handled 23-digit numbers and performed all four arithmetic operations

Grace Murray Hopper
A pioneer in the field. Worked on the Mark I
“It's easier to ask forgiveness than it is to get permission”
Developed COBOL

She remarked that they were “debugging” the system”

ENIAC
In April 1943, the Army contracted with the Moore School to build the Electronic Numerical Integrator and Computer (ENIAC).
John Mauchly led the conceptual design while J. Presper Eckert led the hardware engineering on ENIAC.
Programming was initially accomplished with patch cords and switches, and reprogramming took days.

Mauchly and Eckert
John Mauchly and J. Presper Eckert designed ENIAC, as well as EDVAC, BINAC, and the UNIVAC I the first commercial computer made in the US.
Together they started the first computer company, the Eckert-Mauchley Computer Corporation (EMCC), and pioneered fundamental computer concepts.
Mauchley’s visit to Atanasoff to see the ABC led to a lawsuit.

Women and Programming Interestingly most of
the programming of the early computers were done by women.
Men built the hardware, women did most of the programming

John Von Neumann
A mathematician who made major contributions to a vast range of fields
Was a key player in the development of the atomic bomb
Credited with developing the stored program concept.
Worked with Mauchley and Eckert on EDVAC

UNIVAC
The UNIVAC I (UNIVersal Automatic Computer I) was the first commercial computer produced in the United States. It was designed principally by J. Presper Eckert and John Mauchly.
Design work was begun by their company, Eckert-Mauchly Computer Corporation, and was completed after the company had been acquired by Remington Rand.
The first UNIVAC was delivered to the United States Census Bureau on March 31, 1951
Department of the Army, Ballistic Research Laboratories
IBM and the Seven Dwarfs In 1964, IBM owned 70% of the computing
market
There were seven other companies producing a competing product: Remington Rand Burroughs NCR Control Data Corporation General Electric RCA Honeywell
IBM 700/7000 Series
The IBM 700/7000 series was a series of large scale (mainframe) computer systems made by IBM through the 1950s and early 1960s http://en.wikipedia.org/wiki/File:Ibm704.gif
IBM 360 Series
The IBM System/360 (S/360) was a mainframe computer system family first announced by IBM on April 7, 1964, and sold between 1964 and 1978
It was the first family of computers designed to cover the complete range of applications, from small to large, both commercial and scientific
The chief architect of the S/360 was Gene Amdahl, and the project was managed by Fred Brooks

The Transistor
Vacuum tubes were extremely unreliable, used too much power and produced too much heat
The transistor was invented in 1947 at Bell Labs by a team led by physicists John Bardeen, Walter Brattain, and William Shockley
http://www.juliantrubin.com/bigten/transistorexperiments.html
The Integrated Circuit
Transistors had become commonplace they were smaller and more reliable than vacuum tubes. But there was a limit on how small you could make each transistor.
Jack Kilby in 1958 working at Texas Instruments realized that all parts of a circuit, not just the transistor, could be made out of silicon by September 12 he had built a working model
In January of 1959, Robert Noyce working at Fairchild Semiconductor also realized a whole circuit could be made on a single chip.

Digital Equipment Corporation Founded by Ken Olsen
and Harlan Anderson in 1958
Sold minicomputers. Probably the most famous were the PDP and VAX computers
In 1984 introduced networking to their computers. They were the 5th company to register a .com domain name.

The Altair
The MITS Altair 8800 was a microcomputer design from 1975 based on the Intel 8080 CPU
The Altair is widely recognized as the spark that led to the microcomputer revolution of the next few years

Microsoft
Established on April 4, 1975 to develop and sell BASIC interpreters for the Altair 8800
IBM awarded a contract to Microsoft to provide a version of the CP/M OS, which was set to be used in the upcoming IBM Personal Computer (IBM PC).
For this deal, Microsoft purchased a CP/M clone called 86-DOS from Seattle Computer Products, branding it as MS-DOS, which IBM rebranded to PC-DOS.

Apple
Apple was established on April 1, 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne
The Apple I personal computer kit was hand-built by Wozniak and first shown to the public at the Homebrew Computer Club
The Lisa in 1983 became the first personal computer sold to the public with a GUI
In 1984, Apple launched the Macintosh.

The IBM Personal Computer, commonly known as the IBM PC was introduced on August 12, 1981.
Made of off the shelf parts and had an open architecture.

Xerox Star
Introduced by Xerox Corporation in 1981. It was the first commercial system to incorporate A bitmapped display A window-based graphical user
interface Icons Folders Mouse Ethernet networking File servers, print servers and e-
mail.
Not meant to be a stand-alone computer, but to be part of an integrated Xerox "personal office system”
http://en.wikipedia.org/wiki/File:Rank_Xerox_8010%2B40_brochure_front.jpg
Influence of the Star
Was the blueprint for what we call a computer today Members of the Apple Lisa team saw Star at its
introduction at NCC '81 and converted their desktop manager to an icon-based interface modeled on the Star
Microsoft worked with Apple Computer to develop several Desk Accessories and other minor pieces of software that were included with early Macintosh system software
Larry Tesler left Xerox to join Apple in 1980 and joined the Lisa team
Charles Simonyi left to join Microsoft in 1981. He later led the development of Microsoft office.
The Internet
The origins of the Internet reach back to research in the 1960s commissioned by the United States government
Today, after more than a century of electric technology, we have extended our central nervous system itself in a global embrace, abolishing both space and time as far as our planet is concerned Marshall McLuhan,
Understanding Media, 1964. http://en.wikipedia.org/wiki/File:Birth_of_the_Internet.jpg
The World Wide Web
Arthur C. Clarke predicted that satellites would one day "bring the accumulated knowledge of the world to our fingertips”
Tim Berners-Lee developed the system that we refer to as the world wide web.
http://en.wikipedia.org/wiki/File:Tim_Berners-Lee.jpg
Cloud Computing
Cloud computing is Internet-based computing, where shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid.
Details are abstracted from the users, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud" that supports them.
The picture on the right is one of Google's data centers in Oregon, which is the size of a football field and holds thousands of servers.

Still a computer, but looks very different. Focuses on one application instead of being general purpose http://www.flickr.com/photos/84018923@N00/338087372/
iPad
A tablet computer designed and developed by Apple marketed as a platform for audio and visual media such as books, periodicals, movies, music, and games, as well as web content
